> Key: MNG-2057
> URL: http://jira.codehaus.org/browse/MNG-2057
> Project: Maven 2 & 3
> Issue Type: Bug
> Components: POM
> Affects Versions: 2.0.2
> Environment: java version "1.5.0_06"
> Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
> Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)
> Microsoft Windows XP [Version 5.1.2600]
> Reporter: Steven Coco
> Assignee: Herve Boutemy
> Attachments: UTF8-BOM-pom.zip

> The Byte-Order mark is optional, and discouraged in the UTF-8 encoding; but the Unicode specification is clear that it is allowed -- if you read the Unicode Standard v4, section 2.6, and Table 2.3, and section 15.9, and table 15.3; it is clear that the BOM is allowed at the start of a UTF-8 file.
> It so happens that this is the way Windows NotePad saves files when you select UTF-8; and Maven will not parse it. I'll attach a small POM saved this way, and I'll put it into a ZIP file to hopefully preserve the encoding. Here is the Maven output:
